Read the passage and answer the questions:

Regionalism in India is rooted in India's diversity of languages, cultures, tribes and religions. It is also encouraged by the geographical concentration of these identity workers in particular regions and fuelled by a sense of regional deprivation. Indian federalism has been a means of accommodating these regional sentiments. After independence, initially the Indian state continued with the British-Indian arrangement, dividing India into large provinces, also called 'Presidencies'. These were large multi-ethnic and multilingual provincial states constituting the major political-administrative units of a semi-federal state called the Union of India. Languages coupled with regional and tribal identity and not religion has therefore provided the most powerful instrument for the formation of ethno-rational identity in India.

The term used for addressing the existence of diversity of languages is

Multi-lingual

The correct answer is Option (1) → Multi-lingual

Multi-lingual directly refers to the presence of multiple languages within a group or society. It perfectly describes the situation mentioned in the passage about India's diverse languages.
